Satan is real

The Bible describes him or likens him to a roaring lion.
1st Peter 5:8---" keep your senses, be watchful! Your adversary, the Devil, walks about like a roaring lion, seeking to devour someone." Christians in particular are Satan's prime target. He already has the unbelievers in his clutches (1st John 5:19).

So true, deceptive situations and persons are everywhere because of the influence of Satan and his demonic forces. Knowing the true God and obeying His commandments is a real safeguard from falling prey to Satan's deceptive snares (John 17:3).
